Description

Technical Field

[0001] This utility model belongs to the field of automotive child seat technology, specifically a side collision protection structure for automotive child safety seats. Background Technology

[0002] A car child safety seat is a vehicle safety device designed specifically for children of different ages. Its core function is to minimize harm to children and ensure their safety while riding in a car through a special structure and fixing method.

[0003] The core function of the side impact protection structure of a car child safety seat is to buffer and disperse the impact force during a side collision, reduce the injury to the child's head, torso and other critical parts, and improve the seat's safety protection capability in side collisions.

[0004] According to traffic accident statistics, side collisions account for a high proportion of car accidents. Because the sides of a vehicle are relatively thin and lack buffer zones like the front and rear, the impact force generated during a collision is transmitted to the vehicle interior almost without attenuation. If a child safety seat lacks side protection, the child's body will directly bear the strong side impact force, posing a great safety hazard. Therefore, a side collision protection structure for car child safety seats is proposed to address the above problems. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Specific implementation examples are given below.

[0026] Please see Figure 1 , Figure 2 , Figure 3This utility model provides a side impact protection structure for a child safety seat, including a base 1; characterized in that: a seat back 11 is fixedly connected to the end of the base 1; a connecting plate 12 is fixedly connected to the side wall of the seat back 11; a buffer groove 13 is formed on the side wall of the connecting plate 12; an inner honeycomb energy-absorbing plate 14 is fixedly connected to the side wall of the buffer groove 13; a middle honeycomb energy-absorbing plate 15 is arranged in front of the inner honeycomb energy-absorbing plate 14; an outer honeycomb energy-absorbing plate 16 is arranged in front of the middle honeycomb energy-absorbing plate 15; multiple sets of linkage mechanisms and elastic buffer column mechanisms are arranged between the inner honeycomb energy-absorbing plate 14 and the middle honeycomb energy-absorbing plate 15, and between the middle honeycomb energy-absorbing plate 15 and the outer honeycomb energy-absorbing plate 16; when the seat encounters a side impact, the outer honeycomb energy-absorbing plate 16 first comes into contact with the impact force, and will quickly deform at the moment of impact, absorbing part of the energy and generating displacement. This displacement is transmitted to the middle honeycomb energy-absorbing plate 15 through the linkage mechanism. Driven by the connecting rod, the honeycomb-shaped energy-absorbing plate 15 tilts to one side around the hinge point, stretching the middle honeycomb-shaped energy-absorbing plate 15. Simultaneously, due to the different points of application of the collision force in the central range, as the collision force spreads from the center, the collision force provides energy to cause the connecting rod between the inner honeycomb-shaped energy-absorbing plate 14 and the middle honeycomb-shaped energy-absorbing plate 15 to tilt in the other direction, stretching the other side of the middle honeycomb-shaped energy-absorbing plate 15. This increases the force-bearing area of ​​the middle honeycomb-shaped energy-absorbing plate 15, dispersing the collision force. At the same time, the elastic buffer column mechanism reduces the collision force transmitted from each layer, achieving a buffering effect and further reducing the transmission of the collision force. The three layers of energy-absorbing plates and buffer columns together form a three-dimensional buffer space, absorbing collision energy in stages. The outermost layer absorbs the initial impact, the middle layer disperses and resists the main collision force, and the inner spring-type buffer column further buffers the remaining impact force, minimizing the final collision force acting on the child seat. This minimizes the impact force on the child, improves the child's safety, and reduces safety hazards.

[0027] Furthermore, such as Figure 3 , Figure 4As shown, the linkage mechanism includes connecting rods 2 fixedly connected to the side walls of the inner honeycomb energy-absorbing plate 14, the middle honeycomb energy-absorbing plate 15, and the outer honeycomb energy-absorbing plate 16; a transmission rod 21 is provided above the connecting rod 2; the connecting rod 2 and the transmission rod 21 are hinged together; through the multiple sets of linkage structures composed of the connecting rod 2 and the transmission rod 21, the inner honeycomb energy-absorbing plate 14, the middle honeycomb energy-absorbing plate 15, and the outer honeycomb energy-absorbing plate 16 are cleverly connected. When the outer honeycomb energy-absorbing plate 16 is deformed by force, the force is transmitted through the linkage, triggering the linkage between the middle honeycomb energy-absorbing plate 15 and the inner honeycomb energy-absorbing plate 14. The linkage quickly tilts around the hinge point and shortens the distance between the inner honeycomb energy-absorbing plate 14, the middle honeycomb energy-absorbing plate 15, and the outer honeycomb energy-absorbing plate 16, increasing the force-bearing area and dispersing the collision force. Through the linkage mechanism, the impact force is gradually reduced, the impact on the seat is reduced, and the anti-collision safety is improved.

[0028] Furthermore, such as Figure 3 As shown, the elastic buffer column mechanism includes a damping sleeve 3 fixed between the inner honeycomb energy-absorbing plate 14, the middle honeycomb energy-absorbing plate 15 and the outer honeycomb energy-absorbing plate 16; a spring 31 is provided inside the damping sleeve 3; the elastic buffer structure composed of the damping sleeve 3 and the spring 31 is evenly distributed between the layers, which can provide a strong buffering force at the moment of collision and gradually consume the collision energy through the damping effect.

[0029] Furthermore, such as Figure 3 As shown, the outer honeycomb energy-absorbing plate 16 is provided with a pressure airbag 4 on its side wall. Before the outer honeycomb energy-absorbing plate 16 is impacted by an external force, the pressure airbag 4 receives the impact force first. When the pressure reaches the trigger value, the pressure airbag 4 expands rapidly under the action of gas filling, forming a soft buffer barrier to absorb and consume collision energy and reduce subsequent impact force.

[0030] Furthermore, such as Figure 3 As shown, a limiting frame 5 is fixed to the side wall of the outer honeycomb energy-absorbing plate 16; when the pressure airbag 4 is inflated, the limiting frame 5 limits the range so that the inflation of the pressure airbag 4 is limited to the width range, thereby improving the effect of mitigating the impact force.

[0031] Furthermore, such as Figure 3As shown, the inner honeycomb energy-absorbing panel 14 is made of high-strength plastic; the middle honeycomb energy-absorbing panel 15 is made of high-strength aluminum alloy; and the outer honeycomb energy-absorbing panel 16 is made of EVA foam. By selecting different materials for the inner, middle, and outer honeycomb energy-absorbing panels 14, they have different hardness levels. The outer honeycomb energy-absorbing panel 16 deforms rapidly upon impact, absorbing the initial impact force and slowing the transmission speed of the impact energy. The middle honeycomb energy-absorbing panel 15, with its high strength, disperses the main impact force, and the inner honeycomb energy-absorbing panel 14 buffers the remaining impact force, significantly improving the overall protective effect.

[0032] Working principle: When the seat encounters a side impact, the outer honeycomb energy-absorbing plate 16 first comes into contact with the impact force and deforms rapidly at the moment of impact, absorbing some energy and generating displacement. This displacement is transmitted to the middle honeycomb energy-absorbing plate 15 through a linkage mechanism. Under the push of the linkage, the middle honeycomb energy-absorbing plate 15 tilts and stretches to one side about the hinge point. At the same time, due to the different points of application of the impact force in the middle range, as the impact force spreads from the middle, the impact force provides energy to cause the linkage between the inner honeycomb energy-absorbing plate 14 and the middle honeycomb energy-absorbing plate 15 to... The other side of the middle honeycomb energy-absorbing plate 15 is stretched at an angle, thereby increasing the force-bearing area of ​​the middle honeycomb energy-absorbing plate 15 and dispersing the collision force. At the same time, the elastic buffer column mechanism reduces the collision force transmitted between layers, playing a buffering role and further reducing the transmission of collision force. Through a multi-link structure composed of connecting rod 2 and transmission rod 21, the inner honeycomb energy-absorbing plate 14, the middle honeycomb energy-absorbing plate 15 and the outer honeycomb energy-absorbing plate 16 are cleverly connected. When the outer honeycomb energy-absorbing plate 16 is deformed by force, the force is transmitted through the link, triggering the middle honeycomb energy-absorbing plate 15 and the inner honeycomb energy-absorbing plate 16. The linkage of the energy-absorbing plate 14 structure rapidly tilts around the hinge point, shortening the distance between the inner honeycomb energy-absorbing plate 14, the middle honeycomb energy-absorbing plate 15, and the outer honeycomb energy-absorbing plate 16, increasing the force-bearing area and dispersing the impact force. Through the elastic buffer structure composed of the damping sleeve 3 and the spring 31, evenly distributed between the layers, it can provide strong buffering force at the moment of impact. Before the outer honeycomb energy-absorbing plate 16 is impacted by external force, the pressure airbag 4 receives the impact force first. When the pressure reaches the trigger value, the pressure airbag 4 rapidly expands under the action of gas filling, forming a flexible... A soft buffer barrier absorbs and dissipates collision energy. When the pressure airbag 4 inflates, the range is limited by the limiting frame 5, so that the inflation effect of the pressure airbag 4 is limited to a wide range. The inner honeycomb energy-absorbing plate 14, the middle honeycomb energy-absorbing plate 15 and the outer honeycomb energy-absorbing plate 16 are made of different materials with different hardness. The outer honeycomb energy-absorbing plate 16 deforms rapidly at the moment of collision, absorbing the initial impact force and slowing down the transmission speed of collision energy. The middle honeycomb energy-absorbing plate 15 disperses the main impact force with its high strength characteristics, and the inner honeycomb energy-absorbing plate 14 buffers the remaining impact force.
